| Summary: Java Concurrency Tools for the JVM | |
This project aims to offer some concurrent data structures currently missing from the JDK: * SPSC/MPSC/SPMC/MPMC Bounded lock free queues * SPSC/MPSC Unbounded lock free queues * Alternative interfaces for queues * Offheap concurrent ring buffer for ITC/IPC purposes * Single Writer Map/Set implementations * Low contention stats counters * Executor
Apache-2.0
* Thu Dec 05 2024 Fridrich Strba <fstrba@suse.com>
- Update to 4.0.5
* This is a major release, following the removal of the
'QueueFactory', 'AtomicQueueFactory' and
'org.jctools.queues.spec' package(deprecated since 3.0).
These classes are still used for testing, but are not part of
the release artifacts anymore.
New unpadded queue variants are also included in this release.
* Further changes included:
+ Fix table-size long math on very large tables
+ #355 Adher to size semantic for queue emptiness for
MpscLinkedArrayQueue variants
+ Same code, new bundling post #370
- Removed patches:
* imports.patch
* jctools-javadoc.patch
+ not needed anymore
* Wed Feb 21 2024 Gus Kenion <gus.kenion@suse.com>
- Use %patch -P N instead of deprecated %patchN.
* Thu Oct 26 2023 Fridrich Strba <fstrba@suse.com>
- Added patch:
* jctools-javadoc.patch
+ work around javadoc breakages with jdk 21
* Sat Sep 09 2023 Fridrich Strba <fstrba@suse.com>
- Reproducible builds: use SOURCE_DATE_EPOCH for timestamp
* Wed Mar 23 2022 Fridrich Strba <fstrba@suse.com>
- Build with java source and target levels 8
* Thu Mar 10 2022 Fridrich Strba <fstrba@suse.com>
- Upgrade to 3.3.0
* API Changes:
+ Removed MpscLinkedQueue7 and MpscLinkedQueue8 and consolidated
into parent. This removes the need for the builder method on
MpscLinkedQueue.
+ Deprecated QueueFactory and spec package classes. These are
not used by any users AFAICT and are only used for testing
internally.
+ Removed some internal classes and reduced visibility of
internal utilities where practical. The @InternalAPI
tagging annotation is also used more extensively to discourage
dependency.
+ #226: XADD unbounded mpsc/mpmc queue: highly scalable linked
array queues
+ New blocking consumer MPSC
* Bug fixes:
+ #334 NBHMLong iterators do not remove NO_KEY
+ #335 NBHM/Long/Identity iterators only removes keys if values
have not changed. Now follow JDK convention.
+ #336 MpscBlockingConsumerArrayQueue: fix race writing to
blocked field
+ #339 'fill' wakeup call can spin forever (or until a consumer
is blocked again) on MpscBlockingConsumerArrayQueue
+ #319 Relying on test cases provided by #328 we apply the fix
used for #205 to 'NonBlockingHashMapLong' and
'NonBlockingIdentityHashMap' to provide 'getAndSet' like
semantics for put and remove.
+ #330 Fix a 'NonBlockingIdentityHashMap' 'replace' bug. During
this fix some further work was done to bring the code closer
in line to the current state of 'NonBlockingHashMap'
+ Use byte fields for padding (avoid upcoming false sharing
problem in JDK 15+ where field ordering has changed)
+ #289 Add Automatic-Module-Name header to MANIFEST.MF
+ #292 Fix inconsistent isEmpty/poll/peek/offer dynamics for
SpscLinkedQueue
+ Fixed potential for negative queue size for indexed queues and
similar issue with isEmpty
+ #296 Fix peek/relaxedPeek race with poll/offer in MC queues
+ #297 Fix inconsistent size of FF based queues causing
potential size() > capacity()
+ #316 Fix MpscBlockingConsumerArrayQueue::poll(TimeUnit,timeout)
+ #310 Fix MpmcUnboundedXaddArrayQueue::peek/relaxedPeek
can load "future" elements
+ #209: On Arm7, non-volatile long can have unaligned address
leading to error
+ #216: Size of SpscGrowableArrayQueue can exceeds max capacity
+ #241: Protect the producer index in case of OutOfMemoryError
+ #244: Long NBHM AssertionError when replacing missing key
+ Fix argument checks on fill/drain methods
+ Fix LGTM warning, potential int overflow bug
* Enhancements:
+ #326 Xadd queues consumers can help producers
+ #323 Update to latest JCStress (thanks @shipilev )
* Improvements:
+ Don't mark generated linked atomic queues as final
+ #211: Implement batching methods on MpmcArrayQueue
+ #228: Iterator for MpscArrayQueue and MpscUnboundedArrayQueue
+ Iterator support also available for the *ArrayQueue classes
+ #208: MpscLinkedAtomicQueue can be made not final
+ #237: Add scale to exception message to help debug
netty/netty#8916
* New features:
+ #340 MpscBlockingConsumerArrayQueue
+ After long incubation and following a user request (see #321),
we move counters into core
+ Merging some experimental utils and a #264 we add a
'PaddedAtomicLong'
+ #314 MpscBlockingConsumerArrayQueue::offerIfBelowThreshold is
added
- Added patch:
* imports.patch
+ Fix bug in adding of imports that broke build with
javaparser >= 2.15.0
* Tue Oct 01 2019 Fridrich Strba <fstrba@suse.com>
- Initial packaging of jctools 2.1.2
